ospf path selection about inter-area routes

Hi; 

 

I want to ask a simple question about OSPF. I've setup some topologies in which OSPF has treated different on them with regards to path selection on inter-area routes. As I know and even have tested before, if an OSPF router wants to reach an Inter-area route, it sends packets to the closest ABR, regardless of the end-to-end metric. but in some cases I'm facing with different bevavoir. maybe I've tested in different IOSs. so which one is the Cisco OSPF rule about inter-area routes? sending packets to the nearest ABR router or using the path that has lowest metric from the router to the inter-area route itself? tnx.
